Abstract
A core voltage for a core logic region of an integrated circuit is specified by a programmable register on the integrated circuit. Output terminals on the integrated circuit are coupled to the programmable storage location and supply voltage control signals for a voltage regulator to specify the core voltage according to the contents of the programmable register. The output terminals may output a programmable voltage setting or a fixed voltage setting that specifies a default core voltage value, depending on reset conditions.
